function book_uuid_node_features_rebuild_alter in UUID Features Integration 7

Implements hook_uuid_node_features_rebuild_alter().

Replace book parent uuid's with the valid book parameters. As there is no way to guarantee the correct top-down hierarchical order - collect orphan book nodes for post node rebuild processing.
